Displacement

An object have six degree of freedom in space. There are three translational and three rotational Degree of Freedom.

1.       Translation in X (Ux)

2.       Translation in Y (Uy)

3.       Translation in Z (Uz)

4.       Rotation about X (RotX)

5.       Rotation about Y (RotY)

6.       Rotation about Z (RotZ)

We apply support to restrict these DOF. In ANSYS, for Displacement support, we have to select the translational direction to restrict that direction’s movement at a point, edge or face.
